Sliding Fishing Lure With Hidden Hook for Snag-Free Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lures with exposed fishing hooks face issues such as getting caught on underwater obstacles and inconsistent hook penetration due to varying bite forces, and replacing the hook is difficult when it wears out.
Innovation Solution
A lure design featuring a sliding mechanism with a hidden hook that protrudes upon line pulling, using an elastic member to ensure deep hook penetration and easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fishing hook is exposed to the outside in a hard lure, then the hook can easily pierce the fish, but the hook is easily caught on obstacles underwater such as trees and rocks
Solution Approach 1:
The lure body is divided into front body and rear body that can slide relative to each other, creating separate functional zones: the front body houses the hook in a hidden state for obstacle avoidance, while the rear body provides the sliding mechanism. This segmentation allows the hook to transition between hidden and exposed states independently of the lure's movement through water.
Solution Approach 2:
The fishing hook's position is made dynamic rather than fixed. The hook can slide between a hidden position (when the lure is moving through water) and an exposed position (when triggered by fish biting or line pulling). This dynamic positioning resolves the contradiction by adapting the hook's exposure state to the operational context.
2Object-affected harmful factors
If the fishing hook is hidden inside the lure body to prevent entanglement, then the hook is protected from obstacles, but the hook may not protrude normally depending on bite direction and strength
Solution Approach 1:
An elastic member (spring) is introduced as an intermediary between the triggering action (line pulling or fish biting) and the hook protrusion. This spring mechanism amplifies and standardizes the triggering force, ensuring that even weak or angled bites can reliably drive the hook forward. The spring acts as a force multiplier that converts various input forces into consistent hook projection motion.
Solution Approach 2:
The direct mechanical connection between fish biting and hook protrusion is replaced with a spring-based mechanical system. Instead of relying on the fish's bite force alone to push the hook out, the spring stores energy and releases it to propel the hook forward, ensuring consistent penetration regardless of the bite's direction or strength.
3Strength
If the fishing hook is built into the lure body by a structure that makes it difficult to replace, then the hook is securely fixed, but the entire lure stops functioning if the hook wears out
Solution Approach 1:
The lure is segmented into replaceable and non-replaceable components. The front body containing the hook assembly can be separated from the rear body, allowing the hook to be replaced independently while preserving the intact lure body. This segmentation enables maintenance of the expensive lure body while replacing the consumable hook.
Solution Approach 2:
The design allows the hook (a consumable part that wears out) to be discarded and replaced, while the lure body (a valuable component) is recovered and reused. The sliding mechanism and elastic member remain with the lure body, ensuring that only the worn hook needs replacement rather than the entire lure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents hook entanglement with obstacles and ensures deep hook penetration into fish, with the ability to easily replace the hook when worn out.
Implementation Method 1
an elastic member, and the elastic member may urge the front body and the rear body in opposite directions from each other

AI summary
A lure according to the present disclosure includes, for example, a front body, a fishing hook locked to the front body, and a rear body having a groove portion, wherein the groove portion of the rear body hides at least a part of the fishing hook, the front body and the rear body are connected to be relatively slidable, and when the front body and the rear bod relatively slide, the fishing hook protrudes from the rear body.
